TO ALLAWHOM IT MAY OONCERN:

v Be it known that I, AUGUST ZINSSER, of the city of New York, county and Stat-e of New York, have invented a new and improved Tapping-Picce and I do hereby declare the following to be a full, clear, and exact description thereof, enabling those skilled inthe art to make and use the same, reference being had to the accompanying drawing forming part of this specification, inwhich drawing-- Figure 1 is an axial section-cfa tapping-piece, made according to my invention.

Figure 2 is a perspective of the tapping-piece.

This invention relates to tapping-pieces or spouts, usually applied to barrels and other vessels at or around the bung-hole, for thepurpose of pouring liquids without Wastage ordripping. Tapping-pieces for barrels and other vessels have heretofore-been made by'nailing an apron of leather or other flexible material'below and around thebung-hole or place ofdischarge, or by forming a spout or tube of sheet metal, anddriving one end into the bung-hole or into the solid wood around the bung-hole. Among the disadvantages of the leather tappingpiece are, that it is dicult to make it tight, `that it easily becomesbent out of the pro-per shape, and

thatit'cannot be used a second time with convenience. One of the disadvantages of the sheet-metal tappingpiece is, that its outer edge becomes battered and bent up by the blows required to drive it into its place, and it verysoon becomes unfit for use.; and another is, that the part driven into the barrel easily becomes bent and wrinkled, so as to leak. These several disadvantages are obviated, by myfimproved,tapping-pieces, which are made by 'casting them, a screwthread being formed on the end which enters the barrel, and their sides being provided with ears, to facilitate the operation of screwing' them into their places.

'.lhe letter A designates a tapping-piece, made according to my invention. It is made by casting itof iron, or other suitable metal,l with a screw-thread, B, on its taper end, and with ears, D D, on opposite sides of its' larger end, which ears are intended to facilitate the screwing of the article intoI a bung-hole or other opening, by providing a good grasping-surface-for the hand v l The discharging-end of the tapping-piece is inclined at an angle in the usual way, as indicated by the letter C. Tapping-pieces made according to my invention are not easily broken, and they can be driven with- 'out danger of turning up their edges, asin the case of those made vof sheet metal. They can, furthermore, l

by means vof the screw-thread, be fitted toa barrelso as to make a tight joint, through which 'the liquid contents of the barrel cannot leak, and they can be reroved from an empty, barrel for use with a full one by merely'unscrewing them, thc ears D D enabling the operative to seize lthe article with affirm grasp.

I t will be observed that my improved' tapping-piece is of a character to resist wear and injury, and that its value and efiiciency are not irr'xpairedeby constant use.

What I claim as new, and desire to secure by Letters Patent, is-- The cast-iron tapping-piece A, with a screw-thread B, and ears D D, substantially as shown.

This specification signed by me, this Sd'day of February, 1868.
